ENVELOP SPECIFICATION forming part of Letters Patent No. 794,720, datedJuly 18, 1905.

Application flied May 19, 1904:. Serial No. 208,760.

To (all whom it may concern:

Be it known that I, JOHN W. KUEBLEE, a citizen of the United States,residing at Mankato, in the county of Blue Earth and State of Minnesota,have invented a new and useful Envelop, of which the following is aspecification. f

This invention relates more particularly to means for effecting theremoval of the contents of an envelop therefrom when said envelop isopened, and the object is to provide a simple structure which can bereadily manufactured at small cost and by means of which the entirecontents of an envelop can be eX- peditiously removed when said envelopis opened. l

The form of construction whichA at present is considered the preferableone is illustrated in the accompanying drawings, but is open to changeand modification, as will be apparent.

In the drawings, Figure 1 is a plan view of the envelop-blank with theimprovements applied thereto. Fig. 2 is a vertical sectional viewthrough the envelop after the blank has been folded to proper form. Fig.3 is a sectional view taken on the line 3 3 of Fig. 2. Fig. iis asimilar view on the linellcl of Fig. 2. Fig. 5 is a detail rearelevation of a portion of the envelop, and Fig. 6 is a detail sectionalview taken on'the'line 6 6 of Fig. 5.

Similar reference-numerals are employed to designate similar partsthroughout the several figures. f

In the structure illustrated an envelop is employed preferablycomprising a front wall 7 and a rear wall 8 coeXtensive in sizetherewith. The front wall 7 has end iiaps 9, which are inturned andsuitably secured to the cor. responding end margins of the rear wall 8.The envelop thus has an upper open mouth adapted to be closed by theusual iap 10. The upper ends of the flaps 9 preferably have tabs 11,which are secured over the outer face of the rear wall and reinforce thesame. So far as thus described the Aparts are well known and can bechanged as desired. For that matter the usual envelop, the rear wall ofwhich comprises separate flaps, may be employed in place of that shown.The improvements are as follows: A lining 12, formed, preferably, of

l tissue orV other very thin paper, is folded and located within theenvelop, so that its mouth will open in the same direction as the mouthof said envelop. Its upper edges are preferably secured to the front andrear walls by lines of mucilage 13- or in any other suitable manner.Removing means for the lining is provided, said means consisting of athread or iiexible element, one end portion 14 of which extendsdiagonally inward from one corner of the lining and is secured theretoby a strip 15 overlying the same. At said corner the removing device isformed into a loop or eye 16, and the said device then extendslongitudinally along the outer face of the lining contiguous to theadjacent secured edge, as shown at 17. At the opposite corner anotherloop 18 is formed, and the end portion 19 of the thread lies looselybetween the lining and the wall 8. The eyes 16 and 18 as a result aresecured between the ends of the wall 8 and the flaps 9, and when theenvelop is set up the eyes will as a consequence be located at the uppercorners thereof. The said envelop is used in the ordinary mannerdthat isto say, the contents are introduced through the open mouth thereof,after which the Hap 10 is sealed.

It will be apparent that the lining constitutes no obstruction to theintroduction of the contents, nor does the removing device or thread,thev latter being located between the lining and the wall and the formerhaving its upper edges secured. While this is not strictly borne out bythe drawings, particularly Fig.

'2, it will be apparent that in practice such is the case. It has beennecessary to exaggerate in the drawings the thickness of the variouselements in order to properly show the same.

To remove the contents, one of the upper corners of the envelop,preferably that containing the loop 18, is grasped between the fingersand torn 0H. T he said loop 18 will thus be held in the fingers, andupon pulling the same the portion 17 of the thread will tear through thelining 12 at its point of attachment and through the folded iiap 10 ofthe envelop. When the opposite corner of the envelop has been reached, acontinued pull upon the thread will cause the doubled lining IOO to bewithdrawn through the now opened envelop, thereby removing the contents.

It will be apparent by reference to Fig. 1 that an envelop with theimprovements may be readily and cheaply manufactured, and it willfurthermore be clear that with such improvements not only is the envelopopened, but the contents thereof may be completely and expeditiouslyremoved.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention. Forinstance, as already stated, the shape and construction of the envelopitself may be varied, and yet the removing means can be placed thereinwithout material expense or trouble.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

y1. rlhe combination with an envelop, of a contents-ejector lininglocated in the envelop and secured thereto, and means for opening theenvelop, detaching portions of the lining therefrom, and removing saidejector.

2. The combination with an envelop, of a removable contents-receivinglining located therein and secured to the envelop, and means fordetaching certain of the secured portions of the lining from the envelopand also removing said lining and the contents contained therein fromsaid envelop.

3. The combination with an envelop, of a removable contents-receivinglining' located therein and secured to the envelop, and a flexibledetaching device extending between the lining and envelop and attachedto the said lining, Said device constituting means for detaching asecured portion of the lining from the envelop and also for removingsaid lining from said envelop.

4. The combination with an envelop having an open mouth, of afoldedlininglocated within the envelop and secured along its edges on oppositesides of the mouth, a thread secured to one side of the lining,saidthread having' a portion located between the lining and the envelopand extending longitudinally along one of the secured edges,constituting means for detaching said secured edge from the envelop andalso for removing the lining from said envelop.

5. The combination with an envelop having an open mouth and asealing-flap therefor, of

a folded lining located within the envelop and having its upper edgessecured to the opposite inner faces of said envelop vcontiguous to itsmouth, and a removing cord or thread secured having its upper edgessecured to the opposite inner faces of the envelop contiguous to themouth thereof and comprising the sole fastening means between the liningand the envelop, and a thread having an end portion extending inwardlyfrom one corner of the lining and secured to the outer face thereof andhaving its opposite end portion loosely located within the envelop, saidthread being looped at the opposite ends of the lining, said loops beingarranged'contiguous to the end margins of the envelop and sealed withinthe same.

7. The combination with an envelop, of a lining removably locatedtherein and constituting a container for the contents of the envelop,and an envelop-opening device located between the lining and envelop andsecured to said lining said opening device constituting releasing andremoving means for the lining.

8. The combination with an envelop having an open mouth and a flap forclosing said mouth, of a folded lining located within the envelop andhaving its longitudinal edges secured to the opposite faces of the sameadjacent to said mouth, and a flexible lining-removing device andenvelop-opener extending longitudinally along the secured margin of thelining between said lining and the envelop, said device being attachedto thelining.

9. In combination with the envelop, a removable lining contained thereinand arranged to remove the contents of the envelop when the lining isremoved, said lining being fastened to the envelop at a plurality ofpoints, and means for severing the lining from the envelop at one point,also severing the envelop, and finally removing the lining from theenvelop.

In testimonyT that l claim the foregoing as my own l have hereto affixedmy signature in the presence of two witnesses.
